To all whom it may concern.-

Be it known that I, HANS SIBER, manager,-

captain, emtd, a subject of the King of Prussia, German Emperor, residing at Sommerda, Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Means for Connecting the Barrels of Double-Barreled Sporting-Guns and the Like with the Breech-Piece; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Thisinventionhasforits objectanimproved means for connecting the barrels of doublebarreled sporting-guns and the like with the barrel-lug, and it is a question of forming such a connection that a mechanical coupling of the barrels with the barrel-lug or closingpieoe takes place by the assistance of soft soldering. Such barrel joints or connections are already frequently known, which, however, fulfil their object in only a more or less complete manner. The present barrel connection, however, has an essentially greater solidity than these older arrangements, and the same affords an additional security against unintentional loosening of the barrels, even when the solder is temporarily removed from the respective parts of the barrel by extraordinary heating. This security is effected by a separate insertion or looking bar, which is inserted after the connection of the barrels with the barrel-lug and which holds the latter from both sides by means of dovetail-shaped pro jections engagingin suitable grooves,whereby the barrels are themselves immovably fixed on the barrel-lug. This improved method of arrangement is shown in the accompanying drawings, in which' Figure l is a side view of the barrel and barrel-lug; Fig. 2, afront view; Fig. 3, aplan view of the same. Fig. 4 shows the parts when separated. Figs. 5 and 6 are respectively a plan View and side View of one of the barrels. Figs. 7 and 8 are respectively a view from beneath and a plan view of the fixing-bar.

Each of the two barrels aandbis provided with two sets of dovetail-shaped projections and corresponding grooves standing at right angles to one another. In the form of construction shown the barrels have each two projections or lugs 3 and 4 underneath, while on the sides which face one another they have grooves or channels 1 and 2. The grooves or In order to obtain the final connection, or

rather to more particularly secure the connection, an insertion-piece or locking-bar d, provided on both sides with two dovetailshaped projections d C1 is employed. The projections d 01 fit in the side grooves l and 2 of the barrels, so that when these latter have been mounted upon the barrel-lug the locking-bar can be inserted from above. In its inserted position this then holds both barrels together, while at the same time securing their fixed position on the barrel-lug. The hook-shaped projections or hooks situated on the front and rear ends of the locking-bar d, the arrangement and form of which projections are shown more particularly in Fig. 8,

are intended for increasing the security of the permanent fixing and simultaneously for receiving and distributing the recoil in a straight line over the whole system.

What I claim is- 1. The combination, with two laterallyslidable gun-barrels, and a barrel-lug connected to one side of each of them; of a vertically-slidable locking-bar which secures the said barrels together and prevents them from sliding laterally on the said barreHug, said lug, bar and barrels being provided with interlocking portions on their adjacent surfaces, substantially as set forth.

2. The combination, with two gun-barrels, of a barrel-lug secured on one side of the said barrels, and a locking-bar secured between the said barrels and provided with projections at its ends which engage with the central portion of the said barrel-lug, substantially as set forth.

In testimony whereof I affix my signature in presence of two-witnesses.

HANS SIBER.
